J-Web User Interface for EX-series Switches Overview

Use the J-Web user interface to configure, monitor, maintain and troubleshoot EX-series switches. You can navigate the J-Web interface, scroll pages, and expand and collapse elements as you do in a typical Web browser interface.

Use Internet Explorer version 6.0 and higher, or Firefox version 2.0 and higher to access the J-Web interface.

Note: The browser and the network should support receiving and processing HTTP 1.1 GZIP compressed data.

Each page of the J-Web interface is divided into panes.

The layout of the panes allows you to quickly navigate through the interface. Table 1 summarizes the elements of the J-Web interface.

The J-Web interface provides a Point and Click editor for advanced configuration options. You can also use the JUNOS CLI configuration mode as a configuration editor to create and modify a complete configuration hierarchy.
